Fig. 2. Stride parameters did not differ significantly between level (open symbols)
and incline (filled symbols) hopping at either speed examined. Time of contact
(tc; squares) decreased significantly between 3.3 m
s1 and 4.2 m s1 on both grades
(P<0.01), while swing phase duration (circles) and stride time
(triangles) did not differ significantly between speeds (P>0.05).
Symbols are offset on the x-axis for clarity. Error bars represent
